Description
Technical Field
The invention relates to the field of A41H, in particular to an edge folding process for manufacturing a trouser edge.
Background
Jeans are tight pants worn by men and women, have the characteristics of wear resistance, dirt resistance, close fitting, comfort and the like, are originally appeared in the western United states and are once popular among local miners and jeans, are still very popular in the present generation, and are popular among young people because of wear resistance and soft fabric, are fashionable and comfortable when worn on the body and are popular among young people.
The prior clothes with various styles are sewn in a wired mode, the line type strips of the clothes with the seams in the prior art are clear, particularly the trousers are in the shape of trousers, the edges of the clothes sewn by the side bone edges of the trouser legs are easy to break due to the scattered yarns of cloth, the trouser body is easy to wrinkle, the line type of the sewed line type on the trouser waist edge in the trouser waist is more prominent, and the phenomenon that the waist of a human body is bound with a trace, scratched and the like is easy to appear after the people wear the trousers for a long time; the phenomenon is more obvious particularly in children's clothes, women's clothes, underwear and sportsman's clothes doing high-speed sports for a long time. Not only the appearance is not beautiful and uneven, but also the appearance is uncomfortable.
Meanwhile, due to the fact that the fabric has a certain shrinkage rate after being washed, if the fabric which is just woven is processed into clothes, the size of the processed clothes is very small compared with the size which is customized in advance, so that defective products caused by unqualified sizes often appear after the clothes are processed into finished products, and the cost of clothes production is greatly wasted.
Aiming at the situation, the invention provides an edge folding process for manufacturing the edges of the trousers, so that the edges of the trousers, which are sewn by the side bone edges of the trouser legs, are neat, flat, simple and beautiful.
